Abstract High costs of tree planting are a barrier to meeting global forest restoration targets. Natural regeneration is more cost‐effective than planting, but its potential foster at scale poorly understood. We predict, map, and quantify natural within 75.5 M ha deforested lands in the Brazilian Atlantic Forest. Of 34.1 (26.4%) current cover, 2.7 (8.0%) regenerated naturally from 1996 2015. estimate that another 2.8 could regenerate by 2035, further 18.8 be restored using assisted methods,...
Abstract Studies showed that Brazilian Amazon indigenous territories (ITs) are efficient models for preserving forests by reducing deforestation, fires, and related carbon emissions. Considering the importance of ITs conserving socio-environmental cultural diversity recent climb in we used official remote sensing datasets to analyze deforestation inside outside within Brazil's biome during 2013–2021 period. Deforestation has increased 129% since 2013, followed an increase illegal mining...
Carbon (C) emissions from forest fires in the Amazon during extreme droughts may correspond to more than half of global resulting land cover changes. Despite their relevant contribution, fire-related C are not directly accounted for within national-level inventories or carbon budgets. A fundamental condition quantifying these is have a reliable estimation extent and location types affected by fires. Here, we evaluated relative performance four burned area products (TREES, MCD64A1 c6, GABAM,...
Abstract Fire is one of the main anthropogenic drivers that threatens Amazon. Despite clear link between rainfall and fire, spatial temporal relationship these variables still poorly understood in Here, we stratified Amazon basin according to dry season onset/end investigated its with spatio-temporal variation fire. We used monthly time series active fires from 2003 2019 characterize fire dynamics throughout year identify peak months. More than 50% (32 246) annual mean occurred month. In 52%...
Abstract Timely spatially explicit warning of areas with high fire occurrence probability is an important component strategic plans to prevent and monitor fires within South American (SA) Protected Areas (PAs). In this study, we present a five‐level alert system, which combines both climatological anthropogenic factors, the two main drivers in SA. The levels are: High Alert, Attention, Observation Low Probability. trend number active over past three years accumulated same period were used as...
Abstract: Infrastructure projects and agriculture expansion are increasingly threatening forest conservation in Pará state (Brazil). It becomes necessary to address the implications of these activities on Amazon complex socio-ecological system, considering both material non-material aspects Nature´s Contributions People (NCP). Multiple studies developed future scenarios for Amazon, but only a few have focused discussing positive futures derived from policies interventions based human...
Abstract Studies showed that Brazilian Amazon indigenous territories (Its) are efficient models for preserving forests by reducing deforestation, fires, and related carbon emissions. Here, we used official remote sensing datasets to analyze deforestation inside outside within Brazil's biome in the 2013-2021 period. We found has increased 129% ITs since 2013, followed an increase illegal mining areas. In 2019-2021 period, was 195% higher 30% further from borders towards interior of than...
Fires affect the Amazon rainforest and cause various socio-environmental problems. Analyses of forest fire dynamics supporting actions to combat prevent fires. However, many studies have reported discrepancies in quantification fire, especially tropics. We evaluated four operational products for estimating burned areas (MAPBIOMAS, MCD64A1, GABAM, GWIS) a part southwestern Brazilian Amazon. used year 2019 as reference assess relative performance each product through stratification by...
Fires are one of the main sources disturbance in fire-sensitive ecosystems such as Amazon. Any attempt to characterize their impacts and establish actions aimed at combating these events presupposes correct identification affected areas. However, accurate mapping burned areas humid tropical forest regions remains a challenging task. In this paper, we evaluate performance four operational BA products (MCD64A1, Fire_cci, GABAM MapBiomas Fogo) on regional scale southwestern Amazon propose new...
Topographic correction methods applied to orbital imagery have been evaluated by several authors. The evaluation criteria based on the correlation decreasing between shade and reflectance at different spectral bands or, in some cases, it has included performance of digital classiï¬ers trying separate speciï¬ c land cover types. Some topographic include sampling procedures original image be corrected results are dependent how they conducted. influence types characterization is frequently...
